MY left blinker doesnt flash (on the Dash)but it works outside. so i figured it was the bulb. But when i found the wire it doesnt have the bulb holder, instead it has a factory clip witch is wired into another harness (that is cut) I cant figure out what this harness is? Could it be for a blinker tach? This is for a 67 with gauges. Thanks for any help.
